Built in 1624, this square watchtower replaced an older tower which was first mentioned in 1478. Historians in the 19th century renamed it "treason tower" in reference to an incident that took place at the height of the Burgundian Wars. According to historical accounts, a handful of terrified guards who were on duty at the time took fright when they saw the confederate army approaching, and fled their post so quickly that they left ropes which aided their escape dangling from the top of the tower, making it incredibly easy for the besiegers to take the castle and ransack the medieval town.
